USPS OIG Spring 2022 Semiannual Report to Congress
"Our investigations team continued to play an important role in keeping the mail safe as well as returning money to the Postal Service. For example, our investigations team worked on a pharmacy kickback scheme, which involved clinics that were paid to send compound pain medications to a specific pharmacy, with formulas solely designed to achieve maximum payment from the workers’ compensation program. This investigation resulted in a $20.5 million cost avoidance to the Postal Service. Another case involved a married couple submitting fraudulent indemnity claims to the Postal Service. The combined restitution was $79,455."
